| Description
| - Cílem práce bylo stadium vlivu délky alkylového řetězce na interkalační proces a na vlastnosti polymer/jíl nanokompozitů. Doposud bylo studováno velké množství polymer/jíl nanokompozitních systémů. Menší pozornost byla zatím věnována PVC/jíl nanokompozitům, ačkoliv polyvinylchlorid (PVC) je jedním z nejlépe prostudovaných a nejčastěji používaných polymerů. Přírodní typ jílu, Cloisite Na+ od firmy Southern Clay Products byl interkalován oktadecylaminem (ODA), dodecylaminem (DDA) a oktylaminem (OA). Interkalace byla založena na ion-dipólové metodě. Studium struktury vychází z rentgenografických záznamů a molekulárních simulací. Velmi významnou je hodnota exfoliační energie, jejíž nízká hodnota vede k lepší exfoliaci silikátových vrstev. Takové interkaláty jsou pak vhodnými prekursory pro vznik nanokompozitních systémů. Hodnoty exfoliační energie zkoumaných vzorků ukazují, že interkaláty na bázi montmorillonit/DDA jsou aplikovatelné pro nanokompozitní systémy a to díky jejich nízké hodnotě exfoliační ene (cs)
- The aim of this paper is the study of influence of the length of chain to the intercalation processes and to the properties of polymer/clay nanocomposites. A lot of polymer/clay nanocomposites have been studied so far. Les attention has been given to PVC/clay nanocomposites, although polyvinylchloride (PVC) is the best known and the most widely used vinyl plastic. Natural type of montmorillonite, Cloisite Na+ from Southern Clay Products, was intercalated with octadecylamine (ODA), dodecylamine (DDA) and octylamine (OA) molecules to determine applicability of these intercalates for nanocomposite materials. Intercalation based on ion-dipole interaction was investigated. The structure was determined on the base of X-ray diffraction and molecular simulations. The most important is the value of exfoliation energy. Low values of exfoliation energies lead to better exfoliation of silicate layers. It follows that this material is suitable precursor for polymer clay nanocomposites. The values of exfoliation en
